Nature-based solutions (NbS) address socio-environmental challenges by sustainably managing ecosystems that offer and support the delivery of various services. NbS can integrate locally relevant options for maintaining ecosystems, thus, encourages the participation of local stakeholders. For instance, mangroves referred here as “blue carbon ecosystem infrastructures” (BCEIs), are being reforested by local stakeholders because of their role in coastal protection and, increasingly, for their contribution to global carbon sequestration. This study examined two mangrove eco-parks in Panay Island, Philippines using perception surveys to (1) offer empirical evidence of the impacts of well-implemented BCEIs, (2) obtain conceptual implications of NbS, and (3) provide practical prospects for BCEI applications in the country. Results show that respondents who access the eco-parks have higher awareness compared to people who did not use it, suggesting eco-parks can promote mangrove awareness. Local's utilization of provisioning and cultural services of the eco-parks indicates that mangroves can be a valuable income source. Engaging residents in the management of eco-parks boosts their participation and willingness to lead. The mutualistic relationship between locals and mangroves observed in this study implies the positive effect of BCEI in the country particularly on people’s well-being, coastal protection, and climate change mitigation if implemented and maintained successfully.
